Google+ could have 18 million subscribers; nearly 57% are male

During its quarterly investors conference call last week, Google execs affirmed that Google+ already has 10 million subscribers and growing. Well, it possibly nearly doubled already in less than seven days.

Ancestry.com founder and self-described “serial entrepreneur” Paul Allen previously reported (ahead of Google's official announcement) that the brand-new social networking site had 10 million members. Given that the estimate turned out to be true, let's take a look at his next prediction.

Allen posted to his Google+ page yesterday that his "new-and-improved" surname formula process shows that "more than 750,000 people joined the site on Monday, bringing the total user base to just under 18 million."

Additionally, Experian Hitwise recently published the following statistics. Although some of them might come across as disappointing for a company as enormous as Google, remember that Google+ is only a few weeks old and still not open to the general public just yet.

Google+ (plus.google.com) ranked as the #42 most visited social networking site in the US for the week ending July 16, 2011

Ranked as the 638th most visited site among all sites in the US last week (July 16th) --- up from its previous ranking as the 2404th most visited site in the US the previous week (July 9th)

Received more than 1.8 million total visits during the week ending July 16, 2011 --- up 283 percent compared to the previous week and up 821 percent compared to the last week of June

56 percent of upstream traffic to Google+ last week came from other Google properties

34 percent of upstream traffic came from Google.com

37 percent of upstream traffic to Google+ last week came from search engines

21 percent of upstream traffic came from email

Most visits overall last week to Google+ stemmed from Los Angeles, followed by New York City and San Francisco

As for how the current user demographics break down, Hitwise found that 38.37 percent of visits last week came from users aged 25 to 34, and at least 57% of all users were male.

Now that Google+ has mobile apps for both iOS and Android platforms, those numbers will likely increase exponentially by next week. Not to mention once Google opens up the digital doors beyond the current invite-only status.

In comparison, Facebook has 750 million members. But with Google+ growing at this speedy rate, does Facebook have reason to seriously worry?
